To all whom t may concern:

Bewit known that I, Josnrrr J. SMITH, a citizen of the United States;and a resident of Dorchester, in the county of Suffolk and Statelof*l\lassachusetts,.have invented an Improvementin Devices andMechanism for Depositing Coating upon Foodlroducts, of which thefollowing descriptiom'in connection' with the accompanying drawings,v isa specification7 like characters on the drawings representing likeparts.

This invention y relates to devices and mechanism for depositing coatingupon food products andthe-like. p

l In order that theprinciple of the invention maybe readily understood,`I haveqin the accompanying drawings shown asingle embodiment of meansfor depositing' coating upon' food products. i

Inl said drawings Figure l is a vertical longitudinallsection through ahopper or receiver for the coat ingmaterial and parts associatedtherewith and representing 'coating materialV deposited upon one of thefood products;

Fig 2 is a vertical transverse section taken through the said hopperand` associated parts and representing in end elevation the nozzles `orso-called dies through which thematerial is deposited;

, Fig is a -planvieiv of a "portion of one of the placers forpositioning the food fproductsA for receiving the coating material;

Fig. i is -a vertical transverse section through the food product;

`Fig: 5 is a vertical longitudinal section takenv through one of thenozzlesV or socalled dies;

Fig.` 6 isa vertical transverse section taken therethrough;

Fig. 7 is an underneath plan view thereof;

Fig. 8v is a top plan viewV of the nozzle detached from the rest of themechanism-` Fig. 9 is a plan view of oney of the food productsconstructed in accordance with my invention and of substantially fullsize; and

Fig. l() is a side elevation of such food product. V

y"Food products, suchas cakes and the like7 have heretofore had coatingmaterial depositedfthereon mechanically and suchv food products havebeen lof various shapes in- Speccation of Letters` Patent.

cluding circular and elongated'or of the socalled finger or lady fingertype. Mylinvention comprehends novel means for depositing `coating uponfood products ofsuch elongated or linger shape. Y

Obviously my inventionmay be practised by meansoperated partially byhand, aslby employing the so-called` hand bag Vto which a suitablenozzle is attached.

proper shape nozzle in connection Witlra coating machine generallysimilar tofthat disclosed in the patent toIldWard Legler;

means are disclosed for pushing cakes orV likeA products from a` hopperor'receptacle onto a travehngbelt." Such means are pref- `-erablyemployed in connection With or as a part ofA the mechanism herein'-disclosed; but I'have not `illustrated herein such means in detail,since the cakes for other products may be deposited in any 'suitablemanner upon the apron-or other conveyer.

Vthile any suitable iconveyer may beeinployed, `I preferably provide anapron `or belt l ,which issupportedV upon asuitable framing, not hereinshown. Preferably the apron which is endless is of` very consider'- able`length and the cakes or other products lcarried thereby and treated-ivhile thereon are "discharged inea manner noth'erein rep# resented;`The cakes or the like having been suitably deposited or positioned uponythe belt ily-Which is; `preferably intermittently drivenas described inthe said Legler patent; are preferably byf-a pusher Aorplacer movedunder a suitable hopper or receptacle 2 containing the coatingofvvhatever character; as more fully disclosed in said patent. Insteadof providing a placer or pusher of the shape shown in said patent andwhich is adapted for use in connection with circular products, I employa placer of the form represented at 3 in Figs. 2 and 3. r'Iherein I haverepresenteda transverse member' having forwardly eirtending projections4 preferably pointed, as indicated at 5; f and between which areopen-ended recesses l6 of general oblong shape fr and' 'conformingsubstantially'tothe shape-ofthe food product I have; how` ever, chosento illustrate the use of the upon which `the coating is to be placed.The saidppusherorv placer is connected at itsV ends to longitudinallyextendingrods or barsfA which may be operated in the general mannerVshown in the said Legler patent.v

The coating material of "whatever nature is received within the hopper'or receptacle 2, whichis provided in its bottom withza valve Shere shownas'a shaft adapted to be rotated vintermittently in one directionV Y andprovidedfwith a series of through openings 9 for the delivery for thematerial. Positioned above the shaftS and adapted to be reciprocated. insuitable guide ways in the. end 'walls of thehopper or-receptacle' 2 isa plungerv 10 Vpivotally connected at 11 to a lever arm 12v upon a'rockshaft 13 operated in anyisuitable manner,as, for example, byy

means shown inthe said Legler patent. In this-orl in any other suitablemanner, 'the coating material within the hopper or re-i Y cepta'cle l2;is forced-through the openings `inthe. valve 8 when saidzvalve is in theopen position indicated in Fig. 1.

Communicating with the openings through the valve 8 is preferably aseries of nozzles or so-called dies 14: through which the4 coatingmaterial is deposited upon the .foodf` products, one of which visindicated generally at-15 in Figs. V1, 4L, Qand 10. `Heretofore suchnozzle has been providedl merely with an opening circular4 in crosssection. YI'-have,however, provided means whereby Vthe coating materialis deposited upon an elongated product Vin a substantially even mannerfrom end to end thereof.

, It has heretofore been proposed to deposit a coating upon an elongatedfood product, but so far as I ain awarelonly by somemanually manipulateddevice that has been moved from end` to end of-such product.

, igs., 5, 6 and 7, I have representedthe preferred form' ofnozzle orso-called die.

vThereinit is shownfashaving a neck 16 threaded as indicatedat 17 forattachment to the block or plate :18 wherein thevalve S is positioned.`The saidv nozzle is of an elongated form, as-most clearly representedin Figs. 1, 7 .and-8, As appears from said figures,` the opening 19 intothe nozzle-,is

preferably, though not-necessarily, circular. The body portion 20 of thenozzle is, however, substantially flattened. The discharge slot 21ispref'erably enlargedl at its ends 22,

body of the nozzle andvertically.positioned so as to direct theiiowtoward the two ends of the nozzle. The saidpartition or directing meansmay partake of variousforms. p VIn Figs.` 4, 9 and 10,1 have'represented'the completely coated food productV 15. It

is there shown as consistingfof the base 24 composed of cake or thelike, andthe coating` substance 25 having substantially rounded ends 26and a well dened ridge 27 eX- tending lengthwise of the food productVnearlyl from" end'to end thereof and giving a characteristic appearancethereto and serving alsoy as a reinforcement. vSuch ridge isA ofmechanical advantage as a reinforcementV when the` food productslarepacked. one. upon Y anotherl in a` receptacleVV for'v shipment.V It willbexobserved from. a comparison of Figs. 9 and 10 that the surface .ofthe coat-V i ing materialfis generally rounded excepting where theridge27 is provided. Y Through much experimentation I have ascertainedthat if an elongatednozzlebe provided without enlargements at1the endsthereof `the material will be unequallyV distributed over the surfaceofthe food. product. That is to say, the coating will be deposited insuiiicient abundance midlength ofthe food productbut more thinl at the Iends and so asto give a pointed-e ect.; Y

If desired and within the scope of my invention, the nozzle ofthegeneral type or,

form herein representedmay be employed with mechanisms other than thatshown herein and may also be employed `with asog-called hand bagV formechanical application of the coating material to the food product. Y

Having thus described my invention, I desire it to be understood that.although specic terms are employed, they are used insa genericanddescriptive sense and, not

for purposes of limitation, the scope ofthe 1,

invention `being set forth in the following claims:- i, Y Y

1. A- device forapplying coating to food products consisting of adischargemember having an elongated discharge opening that is open from,end to end, said member being provided interi'orlyv with means fordirecting the flowV of the material' toward both ends of said elongateddischarge ,opening.
